Safety instructions

Read the operating instructions carefully and especially observe the safety information.
If you do not follow the safety instructions and information on proper handling in this
manual, we assume no liability for any resulting personal injury or damage to property.
Such cases will invalidate the warranty/guarantee.
a) Persons / Product
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. These may become dangerous playing material
for children.
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high humidity, moisture,
flammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and protect it from any
accidental use. Safe operation can no longer be guaranteed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.
• Also observe the safety and operating instructions of any other devices which are connected to the product.
• The mains socket that the device is plugged into must be easily accessible.
• As power supply, only use the supplied mains adaptor.
• Only connect the power adaptor to a normal mains socket connected to the public supply. Before plugging
in the power adaptor, check whether the voltage stated on the power adaptor complies with the voltage
of your electricity supplier.
• Never connect or disconnect power adaptors if your hands are wet.
• Never unplug the power adaptor from the mains socket by pulling on the cable; always use the grips on
the plug.
• When setting up the product, make sure that the cable is not pinched, kinked or damaged by sharp edges.
• Always lay the cables so that nobody can trip over or become entangled in them. This poses a risk of injury.
• For safety reasons, disconnect the power adaptor from the mains socket during storms.
• Never use the product immediately after it has been brought from a cold room into a warm one. The
condensation generated could destroy the product. The plug-in power supply unit also involves danger to
life by electric shock! Allow the product to reach room temperature before connecting it to the power supply
and putting it to use. This may take several hours.
• Never pour any liquids over electrical devices or put objects filled with liquid right next to the device. If liquid
or an object enters the interior of the device nevertheless, first power down the respective socket (e.g.
switch off circuit breaker) and then pull the mains plug from the mains socket. Do not operate the product
anymore afterwards, but take it to a specialist workshop.
• If the wall plug transformer is damaged, do not touch it; there is danger to life from electric shock! First,
switch off the mains voltage to the mains socket to which the wall plug transformer is connected (switch off
at the corresponding circuit breaker or remove the safety fuse, then switch off at the corresponding RCD
protective switch, so that all poles of the mains socket are disconnected). You can then unplug the wall
plug transformer from the mains socket. Dispose of the faulty wall plug transformer in an environmentally
friendly way; do not use it any more. Replace it with a wall plug transformer of the same design.
• It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must
be avoided under all circumstances.
• Do not listen to excessively loud music over an extended period of time. This may damage your hearing.

Operation

• If needed, the rubber feet included can be attached to the bottom of the product.
• Turn off the all devices that you wish to connect before connecting the cables.
• There are two optical Toslink input sockets (IN 1 (1) and IN 2 (3)) and two coaxial input sockets (IN 3 (4)
and IN 4 (5)) available as digital audio inputs. Connect a Toslink cable to the IN 1 Toslink input socket and
the Toslink socket on your playback device (e.g. DVD player). Connect more playback devices using the
remaining Toslink and coaxial input sockets.
• There are 3 output sockets available on the opposite side. Connect a Toslink cable to the OUT Toslink
socket (7) and the Toslink socket on your digital playback device (e.g. amplifier). Connect an audio stereo
cable with cinch plugs to the R (9) and L (10) cinch output sockets. Headphones or another suitable
playback device can be connected to the 3.5 mm jack output socket (8).
• Connect the low voltage plug on the power adapter included to the 5V/DC, 1A power adapter connection
socket (11). Connect the power adapter to a suitable mains socket. One of the green LEDs (2) turns on
and stays constant. The green LED will flash if there is no audio input signal or if an erroneous signal is
detected. Check the connections you made if the LED control light flashes.
• Turn on your amplifier and select the corresponding audio input.
• Turn on your playback device (e.g. DVD player) and begin playback.
• Press the switch button (6) to select the desired audio source. The green LED control light (2) next to the
input socket of the active audio source turns on.
• Playback takes place simultaneously at the three audio outputs (7, 8, 9, 10).
• Hold the switch button down for approximately 3 seconds to turn off the device. The green (active) LED
goes off.
• Briefly press the switch button to turn the device back on. Next time the device is switched on it will switch
to the most recently used audio source, provided that the power supply was not interrupted.
• Remove the mains plug from the mains socket after use.
